How do your brakes seperate from the rotars?

Question

Rotors, for those of you who are technical.

How do your brakes seperate from your rotors.?

Answer 1

The brake pad doesn't actually completely separate from the rotor on all cars. Some manufacturers maintain a very slight drag to keep the pads warm and dry. If you run through a water puddle with completely cold and wet pads, the friction power to stop the vehicle is quite reduced.

But, to answer your question, it is the shape of the seal between the piston and the body of the caliper that pulls the pad away from the rotor when you release the brakes.

If you are trying to remove the caliper to change pads, there is many different ways they are mounted. Sometimes two bolts from the back, sometimes a wedge is driven between the caliper and spindle to hold them in place. Different manufacturers use different methods!

Answer 2

The rotors are the disks that the calipers clamp onto.  All of the mechanical movements are in the calipers.  

The calipers are hydraulically operated.  Brake pressure causes then to bind onto the rotor.  Easing off the brake lessens the hydraulic pressure and allows the calipers to move away from the rotor.

Answer 3

I would suggest a repair manual before you even attempt this . Your question indicates that you are about to do something you have no idea about. Don`t forget , your brakes are the only thing that can stop the vehicle, and save you and others on the road. Not something worth saving a few bucks on.

Answer 4

What is a rotar??? We don't have them on cars or any other road vehicles.
